For 2G phones on 3.1.2, you may use Blackra1n to jailbreak and BootNeuter to unlock (found in Cydia). Follow the link that adp provided for the restoring process. You may find the 3.1.2 ipsw in the downloads section here on MMi.

Make sure you download the correct version for your phone (don't download a 3G/3GS version, it will give you an error).
